Apple Replaces Retina Label with XDR
October 07, 2019
 
Apple introduced the term XDR on the iPhone 11, which stands for Extreme Dynamic Range. It indicates 800 nits of brightness in high ambient light, 1,200 nits for extreme dynamic range content. The iPhone XS Max maxed out at 625 nits. The XS Max sported a contrast ratio of 1,000,000:1; the iPhone 11 Pro doubles that to 2,000,000:1. Apple also mentions that the Super Retina XDR on the iPhone 11 Pro is up to 15% more efficient by:
 

• Improved communication between the display driver and the display
• More efficient OLED material
• Optimized the panel design

 
Apple said it “intelligently illuminates the fireball-related pixels up to 1200 nits, while the pixels around it stay deep black.”  Typically, UDC improves its material each year, so Apple (Samsung) is taking advantage of the change. DisplayMate’s Dr. Raymond M. Soneira said that Apple has continued to raise the on-screen Absolute Picture Quality and Absolute Color Accuracy of their displays by implementing Precision Factory Display Calibration, moving the overall iPhone 11 Pro Max display performance up to Record Setting Outstanding levels, and setting or matching many Display Performance Records, including Absolute Color Accuracy at a very impressive 0.9 JNCD that is Visually Indistinguishable From Perfect, and almost certainly considerably better than existing Smartphone, 4K UHD TV, Tablet, Laptop and computer monitors.
